I need to detect the event when the browser close BUT I NEED A PROFESSIONAL SOLUTION.

all of the solutions available on the internet (depending on client coordinates and on load and on unload) are fake

There isn't a reliable way to know if a browser has closed.

Browsers crash, operating systems crash, network connections crash.
There are many situations where a browser will not be able to communicate a problem to the server.
Your server application should not rely on being able to tell if the user is still looking at your application.

The best solution is to use the onbeforeunload event however, I suspect it won't work as you want it to. There isn't a great solution to this problem.

There is not one. Session End on the server is your friend for a reason.

Heck, some of my "web browsing" doesn't involve a browser anymore; I'm not sure how much, but I know it's gone up quite a bit.
